Need crystals for TMCC

quote:

My bad! Apparently I have things reversed! Lionel

Trainman did your system work with the following you posted.

6sp-2867-052 26.640 Mhz for the Command Base

6sp-2868-052 27.095 Mhz for the CAB-1

I can't get this set or any other to work.   Only the 27.255 (original in system) works.....any ideas?

How many different crystals were available for TMCC?  G

JAN Crystals or international crystal bot good sources for small order grind

Yes, with the crystals supplied to us from Lionel. It was when we were doing TMCC demos for Lionel at train shows so that there would not be any conflict with anyone else operating TMCC.

I used them on my home layout when I went back to CAB-1 after putting my Legacy set away. They worked fine but I did notice that for some reason the signal strength seemed to be a little weaker and the range was shorter.

I've since gone back to the original crystals.

Hmmm. I bought new Traxxas 27.195 MHz crystals mfg(SIWARD) same as Lionel and they DO NOT work.. The Xmt is 27.195 and the rcv is 26.740 giving the 455 khz spread.

When I put the standards back in works like a charm. Sent a couple sets to Dale to help.

So for now train shows will be a drag with 2 or 3 clubs running on the same frequency. 

I had an issue with third party crystals in that the one for the base did not work but the one for the remote did when paired up with a Lionel OEM crystal.

Check with Lionel parts they have alternate crystal sets available.

There are a total of three sets of crystals listed as available on Lionel's site. Each crystal is listed as $6.00 each.

6SP2867002 26.800 Mhz STANDARD BASE CRYSTAL

6SP2868012 27.255 Mhz STANDARD CAB-1 CRYSTAL

6SP2867052 26.640 Mhz ALTERNATE BASE CRYSTAL

6SP2868022 27.095 Mhz ALTERNATE CAB-1 CRYSTAL

6SP2867022 26.540 Mhz ALTERNATE BASE CRYSTAL

6SP2868022 26.995 Mhz ALTERNATE CAB-1 CRYSTAL

Hope this helps.

Thanks for the info.....Just talked to Lionel, they are all out of stock and can't be re-ordered.

I just checked the Lionel web site parts order page and they take the order. Have you tried that. Sometimes the inventory information can be wrong. I'd try to order them and see if you get a confirmation.

Well, all the alternate CAB-1 crystals are now gone the standard ones are still available. Did anyone get a set of the alternates?
